Hello @Shayanmz12 - thanks for your post! Firstly, check out our New User Guide - it’ll def prove helpful as you get used to the platform!

Once an event’s date/time has come and gone, the “reschedule” option included in the confirmation will not longer be a valid link and the invitee will need to head to your booking page to start over with a new date/time as though they are booking for the first time, again. 

I hope this helps!

Hi @Kelsi at Calendly, thank you! This is exactly what I was looking for.

I couldn’t find this specific answer anywhere in the docs 

I am sorry this wasn’t more clear - and am so glad to have helped!!!
